Abstract [en]

This work provides new perspectives on impact of design effort,consumed resources and design abstraction on hardwareperformance in a high-level synthesis flow. We have shown thatcounter to published literature as well as intuition; more designeffort may not always result in better performance. We developeda kernel that simulates Brownian motion, and investigatedimprovement in hardware performance with design effort atvarious abstraction levels. Our results indicate that a designershould be careful in putting more effort at a particular abstractionlevel. In our case, we achieved best performance/effort ratio atalgorithm level rather than lower abstraction levels. This stronglysuggests that design effort is not always proportional tocorresponding improvement in performance.
